“Tell me again why we’re robbing a children’s party?” “Because, Bill, children’s parties are the Fort Knox of cake, balloons, and poorly guarded presents.” “You said presents.” “Exactly. Tiny boxes. Sloppy wrapping. Emotional chaos. Perfect cover.” “Molly, these are children.” “Children with gifts.” “That distinction is not comforting.” They crouched behind a hedge across from the community hall, dressed as entertainers. Molly wore a purple magician’s cape. Bill wore a foam dinosaur costume with a tail that dragged through the mud. “I still say we should’ve gone as clowns,” Bill whispered. “You hate clowns.” “I hate being a dinosaur more.” “You volunteered for the tail.” “I thought it was detachable.” “It is detachable. From the dinosaur.” Bill peered through the hedge. “How many guards?” “One harassed-looking parent by the door, three toddlers circling the snack table, and a grandmother with the reflexes of a cobra.” “Armed?” “With a handbag.” “Same thing.” Molly unfolded a map. It was drawn on the back of a pizza menu and included several suspiciously large arrows. “Here’s the plan. We enter during the magic show, collect the presents, and exit through the kitchen.” “What if the magician notices?” “I am the magician.” “You’re wearing a cape.” “A cape is ninety percent of magic.” “What’s the other ten percent?” “Confidence and misdirection.” “You have neither.” Molly slapped a glittery top hat onto her head. “Watch and learn.” They approached the hall. A little girl opened the door and stared at Bill’s costume. “Are you a dinosaur?” she asked. “No,” Bill said. “I’m a tax consultant.” “She’s six,” Molly hissed. “I panicked.” Molly crouched. “Would you like to see a magic trick?” The girl nodded. Molly produced a handkerchief, waved it dramatically, and pulled a rubber chicken from behind the girl’s ear. The girl screamed with delight. Five other children charged over. “Excellent,” Molly murmured. “Audience acquired.” “Why is the chicken wearing a wedding ring?” Bill asked. “Don’t ask questions during the performance.” Molly climbed onto a chair. “Ladies and gentlemen, prepare to witness the impossible!” “Can you make my brother disappear?” a boy shouted. “Only temporarily,” Molly said. “And only with paperwork.” As the children gathered around, Bill slipped toward the present table. He picked up a red-wrapped box. A grandmother’s voice cut through the room. “Young man, what are you doing?” Bill froze. “Checking the structural integrity.” “Of the present?” “Very fragile economy.” Molly flung three scarves into the air. “Look! Flying noodles!” Every child turned. Bill stuffed the box under his dinosaur belly. Then the tail began to squeak. “Squeak,” it announced. The grandmother narrowed her eyes. Bill squeaked again, louder. Molly smiled brightly. “That is part of the act.” “What act?” asked the birthday boy. “The exciting one,” Molly said. Bill waddled toward the kitchen, his tail squeaking with every step. Molly followed, juggling rubber chickens. At the exit, Bill glanced down. “Molly, this box is labeled ‘Grandma.’” She stopped. “Put it back.” “Why?” “Because even we have standards.” “Do we?” “Apparently, today we do.” They returned the present, stole two cupcakes, and escaped through the hedge. Bill removed his dinosaur head. “Next time, we rob a bank.” Molly licked frosting from her glove. “Too risky. Banks have cameras.” “And children’s parties don’t?” “Not ones with cake.”
